In an email Wednesday, spokesman Fred Schaible said Hildenbrand, the Senate's assistant majority leader, was now included among those whose pay could be docked if budgets are not submitted to the governor by July 1.

Hildenbrand's first draft of the proposed Constitutional amendment, officially enrolled last month, included 10 House and Senate leaders. The new draft more than doubles that number to include 23 leadership roles.

Schaible said the 10 leadership positions initially included were identified by the Legislative Service Bureau, which helps draft legislation, as easily defined roles.

"After additional review and discussions, we realized that we could expand the list to include the other leadership positions as well," Schaible said.

Hildenbrand, R-Lowell, introduced similar legislation during the 2011-12 session that would have docked all lawmakers' pay for late budgets.

Hildenbrand said the proposal was prompted by years of partisan bickering during former Gov. Jennifer Granholm's tenure, which had produced multiple late or last-minute budgets.

Still, feedback from lawmakers who said they should not be penalized because they are not in leadership positions, and therefore unable to move legislation, led Hildenbrand to more narrowly say who would take a hit.

Because it would amend the state Constitution, Hildenbrand's proposal would require support from two-thirds of all lawmakers to be put on the statewide ballot.
